Abstract
Description
以下に、本発明の第1実施形態に係る配線基板を、図面に基づいて詳細に説明する。
コア基板5は、配線基板3の剛性を高めつつ一対の配線層6間の導通を図るものであり、配線層6を支持する基体7と、基体7に設けられたスルーホールと、該スルーホール内に設けられ、一対の配線層6同士を電気的に接続する筒状のスルーホール導体8と、該スルーホール導体8に取り囲まれた絶縁体9を含んでいる。
一方、コア基板5の上下面には、上述した如く、一対の配線層6が形成されている。
ところで、例えば電子部品2と配線基板3の熱膨張率の違いに起因した熱応力や機械的応力等の応力が配線基板3に印加された場合、第1無機絶縁粒子13a同士が剥離することにより、第1及び第2無機絶縁層11a、11bのクラックが生じることがある。
また、本実施形態の配線基板3においては、図3Bに示すように、第1無機絶縁粒子13aは、粒径が3nm以上15nm以下に設定された第3無機絶縁粒子13cと、粒径が35nm以上110nm以下に設定された第4無機絶縁粒子13dと、を含む。
次に、上述した配線基板3の製造方法を、図4から図7に基づいて説明する。
(1)第1無機絶縁粒子13a及び第2無機絶縁粒子13bを含む固形分と、溶剤とを有する無機絶縁ゾル11xを準備する。
(8)第2樹脂前駆体シート10bxと、第2無機絶縁層11bおよび金属箔14xを有する積層シート16を新たに準備した後、図6Aに示すように、第2樹脂前駆体シート10bx上に積層シート16を積層する。
次に、本発明の第2実施形態に係る配線基板を、図面に基づいて詳細に説明する。なお、上述した第1実施形態と同様の構成に関しては、記載を省略することがある。
次に、本発明の第3実施形態に係る配線基板を含む実装構造体を、図面に基づいて詳細に説明する。なお、上述した第1実施形態及び第2実施形態と同様の構成に関しては、記載を省略する。
金属箔と、無機絶縁粒子からなる第1無機絶縁層と、第1樹脂層と、を備えた積層板を作製し、該積層板を厚み方向に切断して研磨した断面を、電界放出型電子顕微鏡(日本電子製JSM‐7000F)を用いて撮影し、無機絶縁層内部におけるクラックの有無を観察した。
まず、第1無機絶縁粒子を含む第1無機絶縁ゾル及び第2無機絶縁粒子を含む第2無機絶縁ゾルを準備した。
試料1は、図16A及び図16Bに示すように、第1無機絶縁層11a′が形成されており、図16B及び図17Aに示すように、第1無機絶縁粒子13a′が互いに結合している様子が観察された。
